Management of various sensor networks
Software mastering deployed sensor networks is typically a distributed software system. It is mostly
divided into three main parts—a so-called multitier architecture (Figure .). This architec-
ture is used, for example, by Moteworks [], the Tiny Application Sensor Kit (TASK) [], and
EnviSense [].
The mote network tier includes software components implementing routing and OTA flashing
facilities on sensor nodes. Protocols used at the mote tier are XMesh (Moteworks) or the Collection
Tree Protocol (TinyOS .) to provide routing. To support OTA, Deluge or XOTAP (Moteworks)
can be applied. he connection to other networks is mostly established by gateways, for example, the
